Qajar dynasty

The Qajar dynasty was a Persian state that existed from 1789 until 1925 under the rule of a royal family of Turkic origin. The country's official name during this period under Qajar rule was the Sublime State of Iran. Although they initially expanded the country's borders, the dynasty lost many Iranian territories to Russian expansionism and later could not prevent Persia from being occupied by Russian, Ottoman, and British troops during World War I. A coup d'etat overthrew the ruling Shah, Ahmad Shah Qajar, in 1921 and the Qajar monarchy was officially abolished four years later.
